ABSTRACT:
A control device for a vehicle power transmitting apparatus is disclosed, having an electrically controlled differential portion operative to control an operating state of an electric motor to control a differential state, and a shifting portion forming part of a power transmitting path between the electrically controlled differential portion and drive wheels, which can minimize deterioration in power performance and degradation in controllability during the shifting. Shift interval altering means70is provided for altering an interval L from an operation initiation causing an automatic shifting portion20to execute a shifting, to an actual shift initiation depending on a kind of the shifting. This enables an appropriate interval L to be determined for the shifting, thereby obtaining adequate power performance while capable of avoiding a first electric motor M1from operating in a region outside an operating range. Thus, degradation in controllability is minimized.
